The benefit is, I dont need to open a webpage (less data usage or if you are in a slow internet area) or login to a service to add media

I use this all the time instead of opening Radarr and Sonarr

ya, its using SRUDB which only stores couple of months of data

I am looking for a simple lightweight app to get a historical view of bandwidth usage. vnStat shows total usage by hourly to yearly.
